nnsrmnn r VEHICLE "wiinnn Application filed December 19, 1922. Serial No; 607,775.

To all whom it may concern I Be it known thatI, JOSEPH-BERGER, citizen' of the United States, andresident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Resilient Vehicle Wheels, of which the following is a specification.

This invention relatesto vehicle wheels,

and the main object is to provide a wheel equipped with wire spokes,v the latter being capable of longitudinal extension and extending radially from hub of the wheel.

Another object is to provide an lmproved type of resilient wheel which may be adapted to any vehicle, and which is designed so that a section of the wire spokes may be removed without dismantling the entire wheel.

Still another object is to provide disks which guard the spokes from being bent or otherwise injured.

These and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a side elevational view of the improved type of resilient wheel.

Figure 2 is an enlarged sectional view of the wheel taken approximately centrally thru the wheel.

Figure 3 is a front elevational view of one of the spokes.

Figure 4 is a side elevational view of the same.

Figure 5 is an elevational view of the hub, part of the flange being broken away to show the spoke cradles.

Figure 6 is a sectionalelevational view 40 showing the means for securing the disks in place.

Describing the drawing in detail, the numeral 1 indicates the hub of the wheel which has a hole 2 therein thelatter being adapted to be fitted on a vehicle. Annular side flanges 3 are formed on the hub between adjacent members of which a plurality of longitudinal ooves 4: are formed, said grooves provi ing cradles for the spokes.

The spokes of the wheel are separate members and are composed of two stout wires. The lower member has a connecting brace 5 from the ends of which a pair of arms 6 extend upwardly and divergently. The upper ends of said arms have loops 7 formed thereon, said loops being bent'angularly and A inwardly- These loops slidably-receive the arms 8 of the upper spoke member which are also-connected bya brace The arms' 8 of the upperiwire membe'r converge and i have loops 10 at-theinlower ends which re ceive' the arms 6 of the lower member. The. 1 brace" 5 which connects the lower arms 6 are cradledin the grooves i'of thelhub '1 and I I, are retainedin place'by an' 'annular strap '11 which encircles the hub. Saidstia'p is pref?" erably made of a number of sections, the

. purpose of this construction being to expose only part of-spokes in the event of repair.

The outer rim 12 of the wheel is also provided with a plurality of grooves similar to those on the hub and are adapted to cradle the braces 9 of the arms 8.' The opposite spokes extend radially outward and at a tangent from the hub. The tire shown on the drawing has a fiat peripheral face but any type of tire may be used for the purpose.

An annular disk composedof a number of sections .14 is secured to the side of the spokes. Said disk is preferably composed of a number of quadrants which may be detached without disturbing the adjacent sections. The disks are aligned in pairs on each side of the spokes and serve as means for. protecting the spokes from injury. The disk sections are rigidly secured in place on the wheels by bolts 15 which have flanged heads '16 at one end, said head being adapted to shoulder in recesses in the disk sections on one side of the wheel. The bolts pass between the spokes and the threaded ends 17 engage the disk sections on the opposite side of the wheel. 4

The wheel may be readily assembled and dismantled and is far more eflioient than A those in present day use; As a load rests upon the hub, the spokes below the hub will be shortened while those above the hub will be lengthened. As the arms 6 and 8 are angular with respect to the vertical, resistance will be offered to the extension or retraction, as before such action can occur, the angles of the arms must first be changed. When elongated or retracted the arms of the spokes have the tendency to resume the normal position.

When a spoke has become bent or otherwise unserviceable the disk section 14: which covers that particular spoke, may be removed without disturbing the remainder of the disks. After detaching the strap 11 any of the spokes mayv be removed from the wheel. a

I claim 1. A,device of the class described comextending radially outward, a tire encirclingthe outer ends of said spokes, and means for securing the spokes; to. said hub.

2. A- device of the class described comprising a flanged hub having a plurality of grooves on its periphery, spokes cradled in said grooves extending radially and tangentially outward, said spokes being extensible and retractable, a grooved tire encircling said hub and receiving theouter ends of the spokes in its grooves, disk sections secured to the, faces-of the Wheel and adapted to protectthe spokes from injury, and means forthe other member having angular diverging arms, loops on the ends of the arms of each member being adapted to engage the arms of the opposite member, a hub having grooves thereon, the latter being adapted to receive one end of each of said spokes, a strip encircling said hub retaining said spokes in place, a grooved tire receiving the opposite ends of the spokes, and disk sections adapted to partly cover the spokes.

Signed, at- New York, in the county of- New York, and State ofNeW York, this 29 day of November A. D. 1922.

JOSEPH BERGER.
